Reproductive Life History Of Fundulus Jenkensi And Comparative Development Of Five Sympatric Fundulid Species, Eric Thomas Lang

Master's Theses

Fundulus jenkinsi is recognized federally and within the state of Mississippi as a Species of Concern. Little is known about the life history of this coastal killifish, but a detailed reproductive histology study of F. jenkinsi and a diagnostic key of the early life stages of select members of Fundulidae can provide the foundation needed to accurately identify it and quantify reproductive parameters in this rare species in need of conservation. Monthly gonadosomatic index (GSI) of male and female F. jenkinsi were documented, and spawning phases and oocyte stages were examined using reproductive histology. In addition, various stages of …

Cftr From Divergent Species Respond Differently To The Channel Inhibitors Cftrinh-172, Glibenclamide, And Glyh-101, Marie Suzy Bewley

Yale Medicine Thesis Digital Library

Studies of widely diverse species of a protein are a powerful tool to gain information on the structure and function of the protein. We investigated the response of human, pig, shark and killifish cystic fibrosis trans-membrane conductance regulator (CFTR) to specific inhibitors of the channel: CFTRinh-172, GlyH-101, and glibenclamide. In several expression systems, including isolated perfusions of the rectal gland, primary cell cultures of rectal gland tubules and oocyte expression, we observed fundamental differences in the sensitivity to inhibition by these CFTR blockers. We used primarily two-electrode voltage clamping of cRNA microinjected Xenopus laevis oocytes. In oocyte studies, shark CFTR …

Rh Glycoprotein As An Ammonia Transport Molecule, Matthew B. Phillips

College of Graduate Studies: Theses & Dissertations

Fish use their gills to excrete ammonia in order to eliminate nitrogenous waste. We hypothesize that this mechanism is accomplished by one or more transport proteins in the Rh glycoprotein (RhxG) family. Longhorn sculpin (Myoxocephalus octodecemspinosus) cDNA was amplified using polymerase chain reaction (PCR) and then the PCR products were visualized on an agarose gel. The cDNA from the gel bands was then sequenced and the gene sequence fragments were assembled and completed by rapid amplification of the cDNA ends (RACE). By this process we have obtained large portions of the gene sequences of the four known paralogues located in …

Distribution Of Allatostatin C-Like Immunoreactivity In The Central Nervous System Of The Copepod Crustacean Calanus Finmarchicus, Caroline H. Wilson, Andrew E. Christie

Health Sciences and Kinesiology Faculty Articles

The C-type allatostatins (C-ASTs) are a family of highly pleiotropic arthropod neuropeptides. In crustaceans, transcriptomic/mass spectral studies have identified C-ASTs in the nervous systems of many species; the cellular distributions of these peptides remain unknown. Here, the distribution of C-AST was mapped in the nervous system of the copepod Calanus finmarchicus, the major contributor to the North Atlantic’s zooplanktonic biomass; C-AST-immunopositive neurons were identified in the protocerebrum, in several peripheral ganglia associated with feeding appendages, and in the ganglia controlling the swimming legs, with immunopositive axons present throughout the ventral nerve cord. In addition, axons innervating the dorsal longitudinal …

National Collegiate Honors Council Monographs

When Joan Digby first proposed taking collegiate honors students into our national parks, I jumped at the chance. Within minutes of reading her email, I not only responded with an enthusiastic “Yes!” but went so far as to volunteer the resources of the Southern Utah University Honors Program to get things started. Nestled among 5 national parks in southwestern Utah, I felt our campus would be a natural focal point for the kind of program Joan envisioned. Within weeks we had laid the groundwork for a proof-of-concept pilot project at nearby Bryce Canyon National Park. Little did I know at …

Ornithocoprophilous Plants Of Mount Desert Rock, A Remote Bird-Nesting Island In The Gulf Of Maine, U.S.A, Nishanta Rajakaruna, Nathaniel S. Pope, Jose Perez-Orozco, Tanner B. Harris

Biological Sciences

Plants growing on seabird-nesting islands are uniquely adapted to deal with guano-derived soils high in N and P. Such ornithocoprophilous plants found in isolated, oceanic settings provide useful models for ecological and evolutionary investigations. The current study explored the plants found on Mount Desert Rock (MDR), a small seabird-nesting, oceanic island 44 km south of Mount Desert Island (MDI), Hancock County, Maine, U.S.A. Twenty-seven species of vascular plants from ten families were recorded. Analyses of guano-derived soils from the rhizosphere of the three most abundant species from bird-nesting sites of MDR showed significantly higher (P < 0.05) NO₃⁻, available …

A Prognostic Index For Predicting Lymph Node Metastasis In Minor Salivary Gland Cancer, Shane Lloyd

Yale Medicine Thesis Digital Library

We hypothesized that lymph node involvement in minor salivary gland cancers is associated with clinical and pathological factors commonly available to the clinician after a typical initial workup. Our aim was to identify these factors using a dataset that allowed us to compile the largest series of minor salivary gland cancers in the published literature. Using this dataset we also aimed to characterize the distribution of histological types by primary site, identify the predictors of the use of external beam radiation therapy and neck dissection, and examine the effect of lymph node involvement on survival. Using the SEER database, we …

Advances In Serpentine Geoecology: A Retrospective, Nishanta Rajakaruna, Robert S. Boyd

Biological Sciences

(In absence of a text abstract the first paragraph of the paper is provided.)

Serpentine habitats have long provided model settings for geoecological research (reviewed in Alexander et al. 2007, Brady et al. 2005, Brooks 1987, Kazakou et al. 2008, Kruckeberg 1984, Proctor and Woodell 1975, Raja-karuna et al 2009). Serpentine loosely refers to a broad group of minerals associated with the weathering of ultramafi c (high iron and magnesium-rich) rocks found along continental margins and orogenic belts. Soils associated with such rocks often differ from more widespread soils, being less fertile and having high concentrations of some heavy metals. …

Incentives And Disincentives For Day Visitors To Park And Ride Public Transportation At Acadia National Park, Frank Holly

All Theses

Acadia National Park, located on Maine's Mount Desert Island, attracts over 2 million visitors each year (National Park Service, 2009). To protect the park's natural resources and provide for superior visitor experiences, the National Park Service established the fare-free Island Explorer bus service in 1999 to transport visitors around the park and to surrounding destinations on Mount Desert Island. This service has seen a steady increase in annual ridership, and will further expand in the future with the completion of an off-island park-and-ride transit hub called the Acadia Gateway Center. The facility would serve as a place for day visitors …

Differential Response Of Amp Activated Protein Kinase (Ampk) And Hsp70 To Temperature Stress In The Gastropod, Nucella Lapillus, Emily Zimmermann

All Theses And Dissertations

Populations of the gastropod Nucella lapillus are polymorphic for shell color, with light-colored shells predominating on warmer, wave-protected shores and dark-colored shells limited primarily to cooler, wave-exposed shores. During thermal stress, darker shells attain higher body temperatures than lighter shells. These results suggest that heat stress may determine field distribution patterns. However, there is currently little evidence of physiological consequences of thermal stress in these organisms. Following the guiding hypothesis that heat stress leads to cellular energy depletion, we explored whether the central energy regulator AMP-activated Protein Kinase (AMPK) is activated by heat stress. We compared this response in both …

Finfish And Aquatic Invertebrate Pathology Resources For Now And The Future, Jan M. Spitsbergen, Vicki S. Blazer, Paul R. Bowser, Keith C. Cheng, Keith R. Cooper, Timothy K. Cooper, Salvatore Frasca Jr., David B. Groman, Claudia M. Harper, Jerry M. (Mac) Law, Gary D. Marty, Roxanna M. Smolowitz, Judy St. Leger, Douglas C. Wolf, Jeffrey C. Wolf

United States Environmental Protection Agency: Publications

Utilization of finfish and aquatic invertebrates in biomedical research and as environmental sentinels has grown dramatically in recent decades. Likewise the aquaculture of finfish and invertebrates has expanded rapidly worldwide as populations of some aquatic food species and threatened or endangered aquatic species have plummeted due to overharvesting or habitat degradation. This increasing intensive culture and use of aquatic species has heightened the importance of maintaining a sophisticated understanding of pathology of various organ systems of these diverse species. Yet, except for selected species long cultivated in aquaculture, pathology databases and the workforce of highly trained pathologists lag behind those …

The Effect Of Glutamate On Neurite Outgrowth In Fiddler Crab (Uca Pugilator) X-Organ Cells, Ruth B. Langton

Honors Theses

Glutamate is the primary excitatory neurotransmitter in the mammalian central nervous system. It is of particular interest because of its supposed role in the processes of learning and memory, and also because of its potential toxic effects that have been linked to neurodegenerative diseases, such as Alzheimer’s and Parkinson’s. Although glutamate is necessary for normal cell functioning, high levels of glutamate receptor activation can result in cell death, a phenomenon known as excitotoxicity. It has been suggested that glutamate also plays an important role in the insect and crustacean nervous systems, allowing for the examination of excitotoxicity in these organisms. …

Learning The Lay Of Their Land: Data Recording By Maine Land Trusts, Patrick John Roche

Honors Theses

Land trusts have led the recent, rapid expansion in private land conservation in the US. As they have grown, many questions have emerged as to the value of their conservation efforts, especially in the long-term. To address this data gap, studies have evaluated easement restrictions and the characteristics of land trust protected property. I take a novel approach by investigating the data that land trusts record about their protected properties and its impact on their capacity to protect conservation values. I surveyed 55 land trusts operating in Maine about data they record in baseline documentation reports. A majority (82%) had …

Evaluating Acute Toxicity Of Cadmium To Chironomid Using Hemoglobin As A Molecular Biomarker, Jun Taek Oh

Seton Hall University Dissertations and Theses (ETDs)

Effects of cadmium (Cd), a heavy metal contaminant, on hemoglobin were investigated in aquatic midge fly larvae of the Family, Chironomidae. In this study, chironomid populations from one polluted site, Kearny Marsh, New Jersey, two reference sites, North East Creek, and Bass Harbor, ME, and a laboratory population were taxonomically identified and tested for their sensitivity to Cd. Heavy metals in tissue, water and sediment were analyzed using Atomic Absorption Spectroscopy. Water quality at each site was assessed by measuring pH, dissolved oxygen (DO), oxidation-reduction potential ( eH), salinity and temperature. Hemoglobin proteins in individual larvae were easily detected using …
